So nearā¦
I use an encrypted file system and store the encrypted files in a subfolder of my nextcloud folder on a Linux machine. The Nextcloud desktop client syncs these to my server and from there to other desktop clients (Windows and other Linux PCs). If I need to I can then decrypt and access the valuable contents on those other machines.
With the Android Nextcloud client I can manually sync the crypt folder to get a local copy. I can also mark existing files as āfavouritesā and Iāve found that changes to the underlying clear text files will then remain in sync in the background. However, if the encrypted file system on a PC creates a new file it is not marked as a āfavouriteā on the Android client and so will not be synced by the background processing.
It seems to me that for my use case being able to mark a folder as a āfavouriteā such that any new files created in it are automatically marked as āfavouriteā would solve my problem.
One obvious other way around it for me is to use a container file based encrypting file system and mark the container file as āfavouriteā - but that introduces other problems.
For the moment Iām back to using syncthing (which is an excellent utility) in a separate folder branch - but Iād rather consolidate to the brilliant and more generally useful Nextcloud and not have so many apps running on my phone or PCs.
